  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020This is just the UK, SF6 stays in the atmosphere for a minimum 1000 years where as CO2 100 years. SF6 is on the increase the US expect a 6.2% increase over the next 6 years. SF6 might not damage the Ozone but it will accelerate Global Warming given the fact that it stays in the atmosphere longer can cause more damage over a longer period of time.

    A process for selectively etching a substrate 20 having a molybdenum silicide layer 25 with a resist material 26 on portions of the molybdenum silicide layer 25 is described. The substrate 26 is placed into an etch zone 54 and the process gas comprising SF 6 and HBr is introduced into the etch zone 54. Preferably, the volumetric flow ratio of SF 6 :HBr is from about 1:10 to about 1:1, and more

  • Experimental investigation of atomic fluorine and oxygen

    Absolute fluorine atom density investigated using APMS technique, was found to increase with increase in gas pressure in SF6/O2/Ar discharge (70/26/4 %) operated at 100 W rf power. Increase in fluorine atom density can be mainly due to increase in SF6 partial pressure as electron density was found to be in weak correlation with pressure.
